I rather dislike almost all of the FF games, but hear me out. I'm not going to talk about any of the games prior to 7, because it gets confusing and I don't want a giant wall of text.
I disliked FF7 because of its horrible polygonal graphics. Now I'm NOT a graphics whore. I still play old sprite games, in fact, I prefer simpler graphics. But I like them to actually look nice, which is plenty possible with say, Doom quality graphics. FF7 is just too awful looking, at least at the time. The main character looks like a lego! Or pop-eye! His biceps are larger than his head, but everything else about him is skinny... except when you go into turn battles, and then everything looks proper. What the hell? Why didn't they just use the battle model for the exploration mode charcters? Anyway, I love the music in the game, the combat is fun and the story is creative and inventive, but I can't forgive the graphics in this game.
FF8- graphics are great, music is great, story is again creative, but one major flaw.... enemies level up with you - making actually playing the game redundant, in fact... you could just remove xp and levels from the game entirely. . . hell, remove all combat... because it plays like oblivion.
FF9- same story here... but whats this? (oh god, what am i getting into here, the first page of this thread had at least 5 FF9 fanboys...) the graphics are detailed and excellent, but they purposefully chibi-tise all the characters? Ugh, again, I couldn't get past the fact that I was playing characters that didn't look older than 4 or 5 years old, based on their body size. Its just, not fun to me. Another lost opportunity here for a story to be taken seriously with interesting characters, ruined by the style and graphics.
FF10 - I liked this game, except for two small complaints I have with it. Tidus is pronounced Teedus, instead of Tide-us (which I always thought would be cooler, he DOES have an aqua-ish weapon and plays an underwater sport after all...) and the english voice acting is just horrible. Other than that, first Post Nintendo FF game I could stand to invest all the required hours to get invested in the characters and complete the game.
FF10-2 I didn't get a chance to play this game, but from what I can tell it shifted focus onto playing Yuna.
FF11 was an MMORPG and a damn great game, played it for years and still love it.
FF12 was also a great game, voice acting was improved though we almost reverted to playing children again, it does have adult characters and I really liked the new mmo-style battle system. Its like playing a FREE MMO that doesn't require an internet connection or a server, combined with the quality writing, music and characters typical of the FF series.
FF13 didn't get a chance to play this.
FF14 nor this.
Oops, it ended up being a wall of text anyway, oh well. If I had to recommend a game, I would say play Breath of Fire 3 on the Sony Playstation! IMO, a superior turn based game with a lot of re-playability.
